Creating singleton class and use it across your application- android

Here you can find the singleton class which u can use it across your app as a global variable, i use this usually passing the arraylist

package com.example.testSingleton;

/**
 * Created with Sharath yadhav.
 * Date: 13/09/2015
 * Time: 10:36
 */




public class Singleton {

    private static Singleton mInstance = null;



    private String mString;

    private ArrayList<yourclass> menudeatail;





    public ArrayList< yourclass > getMenudeatail() {

  return menudeatail;

 }



 public void setMenudeatail(ArrayList< yourclass > menudeatail) {

  this.menudeatail = menudeatail;

 }



 public static Singleton getInstance(){

        if(mInstance == null)

        {

            mInstance = new Singleton();

        }

        return mInstance;

    }



    public String getString(){

        return this.mString;

    }



    public void setString(String value){

        mString = value;

    }

}
